CÓDIGO 1:
Este codigo se aplica desde un Gadget asi que vamos a crear uno y pegamos dentro el siguiente codigo:

<script type='text/javascript'>var fallObjects=new Array();function newObject(url,height,width){fallObjects[fallObjects.length]=new Array(url,height,width);} var numObjs=20, waft=50, fallSpeed=10, wind=0; newObject("https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKndh8KM-tjqaKlaF4kv9iSsfCf4VbLJoqiaSBfjxVALAkDX9AHuG2_kF7-IeJ5aGSA0GDVTKViu9PH170_WGNp_RboMFO65N2Ia_AgvQpuYalZiywtmBcnvZG2iidoxB6rOC6kBJdLWhO/s400/nieve2_jessi_diyva.png",22,22); newObject("https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQ2t6gmH6RQ8ZPbkZo9gvbKf3rb6RWivMKQvE7fKT21CI8MPQW7Q6Rse4Zc0g22myHnklLdHXTYSmQ7PPckTGvT4Vk9zk8kC2EYzy8EMb-GvkWWpJqlsawFMCeMgY2DvTefLvy721Fm_Cc/s400/nieve1_jessi_diyva.png",22,22); function winSize(){winWidth=(moz)?window.innerWidth-180:document.body.clientWidth-180;winHeight=(moz)?window.innerHeight+500:document.body.clientHeight+500;} function winOfy(){winOffset=(moz)?window.pageYOffset:document.body.scrollTop;} function fallObject(num,vari,nu){objects[num]=new Array(parseInt(Math.random()*(winWidth-waft)),-30,(parseInt(Math.random()*waft))*((Math.random()>0.5)?1:-1),0.02+Math.random()/20,0,1+parseInt(Math.random()*fallSpeed),vari,fallObjects[vari][1],fallObjects[vari][2]);if(nu==1){document.write('<img id="fO'+i+'" style="position:fixed;" src="'+fallObjects[vari][0]+'">'); }}function fall(){for(i=0;i<numObjs;i++){var fallingObject=document.getElementById('fO'+i);if((objects[i][1]>(winHeight-(objects[i][5]+objects[i][7])))||(objects[i][0]>(winWidth-(objects[i][2]+objects[i][8])))){fallObject(i,objects[i][6],0);}objects[i][0]+=wind;objects[i][1]+=objects[i][5];objects[i][4]+=objects[i][3]; with(fallingObject.style){ top=objects[i][1]+winOffset+'px';left=objects[i][0]+(objects[i][2]*Math.cos(objects[i][4]))+'px';}}setTimeout("fall()",31);}var objects=new Array(),winOffset=0,winHeight,winWidth,togvis,moz=(document.getElementById&&!document.all)?1:0;winSize();for (i=0;i<numObjs;i++){fallObject(i,parseInt(Math.random()*fallObjects.length),1);}fall();</script>
ESTE CÓDIGO TIENE IMÁGENES (https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKndh8KM-tjqaKlaF4kv9iSsfCf4VbLJoqiaSBfjxVALAkDX9AHuG2_kF7-IeJ5aGSA0GDVTKViu9PH170_WGNp_RboMFO65N2Ia_AgvQpuYalZiywtmBcnvZG2iidoxB6rOC6kBJdLWhO/s400/nieve2_jessi_diyva.png Y https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhQ2t6gmH6RQ8ZPbkZo9gvbKf3rb6RWivMKQvE7fKT21CI8MPQW7Q6Rse4Zc0g22myHnklLdHXTYSmQ7PPckTGvT4Vk9zk8kC2EYzy8EMb-GvkWWpJqlsawFMCeMgY2DvTefLvy721Fm_Cc/s400/nieve1_jessi_diyva.png) QUE PODEMOS REEMPLAZAR PARA CAMBIARLAS POR LO QUE QUERAMOS. SOLO RESPETA EL TAMAÑO DE LA IMAGEN.

CÓDIGO 2:
VAMOS A TEMA, LUEGO A EDITAR HTML Y AHI DENTRO DEL CODIGO PRESIONAMOS CTRL + F ASI ABRIMOS LA BARRA DE BUSQUEDA Y PONEMOS: </head>Y DAMOS EN ENTER:
AHORA PEGAMOS EL SIGUIENTE CODIGO ANTES DE </head>:

Añadir un gadget y elegimos HTML/Javascript:
